Abstract
Description
The invention relates to a pyromechanical battery pole disconnect element
Pyromechanical battery pole disconnect elements for severing cables, stranded cables, etc. are known in the art. The fundamental principle involves a piston which is driven by a pyrotechnic element generating a propellant gas, whereby a cutter, knife blade, or punch element is located on the operative side of the piston. However, these pyromechanical disconnect elements interact in a fundamental way with the surrounding installation geometry. As a rule, the conductors and the battery terminal clamps mounted on the battery pole are composed of multiple components, an arrangement that makes assembly difficult. Another problematic aspect occurs when thick cable strands are clamped onto the current leads, whereby it is necessary, due to the low-resistance requirement, to attach these cable strands to the current leads using extremely strong terminal screws. When a battery terminal clamp of this type is situated on the battery pole, it is possible for significant mechanical vibrational loads caused by vibrations and shocks from the vehicle to act on these pole terminal clamps. As a result, the conductor may break.
The goal of the invention is therefore to construct a complete conductor, as the battery terminal clamp, in such a way that can be inserted into an armor housing and is kept clear of external mechanical loads at the isolating point. An additional goal according to the invention is to be able to install the pyrotechnic disconnect element and the conductor within a battery terminal clamp housing that is both simple and very securely attached.
According to the invention, this goal is achieved by combining all the current-conducting components except the active element to form a one-piece battery terminal clamp element.
A preferred embodiment is characterized in that the battery terminal clamp element has a clamping device for connection to the battery terminal and in that two arms oriented essentially at right angles to each other extend from the clamping device; in that an isolating point is located on the first arm, and beyond the isolating point and opposite the clamping device a first attachment element is located, which attachment element serves to connect to the systems to be disconnected in an emergency; and in that a second attachment element is located on the second arm and serves to connect to the systems to be disconnected in an emergency.
The housing advantageously has bracing ribs and/or link segments, and the battery terminal clamp element and active element can be inserted into these bracing ribs and/or link segments.
In order to prevent elements from falling out, an enlarged segment is preferably located on the first arm of the battery terminal clamp element between the isolating point and the first attachment element, the enlarged segment being located or pinched between the ribs in the housing.
In a preferred embodiment, the second attachment element is a support screw, and the first attachment element is an attachment hole.
In a preferred embodiment, only the attachment elements protrude from the battery terminal element out of the housing.
The arms of the battery terminal clamp element are advantageously in the form of a ribbon.
To provide reinforcement, the housing of the battery pole disconnect element is preferably fabricated out of a fiber-reinforced plastic.
The invention thus proposes that the complete current-collection terminal, including the pyromechanical isolating point, be inserted into a special support housing in such a way that the internal armoring link segments support the one-piece battery terminal clamp with the isolating point and the pyrotechnic active element such that the entire assembly is accommodated as a compact module within an enclosed housing.
The following discussion explains the invention in more detail based on the figures.
In order to further elucidate the arrangement,
Function: The complete pyromechanical battery pole disconnect element is mounted on the terminal post of the battery using clamping screw 12 in a manner analogous to a collet. At electrical support point 10, a variety of loads can be electrically connected by cable lugs. The load to be disconnected may be connected to the terminal lug or hole 9. The ignition plug connector coming from the sensor system is plugged in at connector plug input 8 of pyromechanical disconnect 7. In the even of a crash, for example, in which the triggering sensor system responds to the vehicle crash signature, an electrical ignition current pulse is connected through to ignition plug connector input 8. Within disconnect element 7, a propulsive pressure builds up which accelerates the disconnect element and drives it onto isolating point 11. As a result of the high kinetic energy liberated upon impact with point 11, the bus bar is broken at this point and bent into the cavity 4 as shown in the drawing. The circuit from the battery through battery terminal 5 to terminal 9 is thus interrupted.
